The term "intellectual patrimony" might be a good one for somepurposes, but if you want people to know you are using it, I suggestyou spell it out in full every time. At present, when people see theabbreviation "IP", they will think "intellectual property".

However, it is usually best to talk about "copyright", or about"patents", or about "trademarks", and avoid generalizations that wouldtend to blur the boundaries. The widespread use of "intellectualproperty" leads people to suppose these laws (and the issues theyraise) are mostly similar, but they are not.
